Earth's mysterious core is yet again generating headlines as scientists learn more about what lies way beneath our feet. Located 3,000 miles below the Earth’s surface, the inner core is anchored ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

This is because the internal solar environment plays an important role in determining the weather in space and also the Earth ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.
